The Dark Matter Mystery [4K]

- Dark Matter is a theoretical form of invisible mass, which is believed to be present in galaxies, but has never been seen or detected. You've probably heard of it before, as it makes up a large part of the physics you find in textbooks. But how can something that's never been seen have so much scientific confidence? Furthermore, why can't we see dark matter to begin with? And if we can't see it, how do we know that it is really there? And if it's not there, what are the alternative ideas? These are the questions we will be aiming to answer, as we dive into the Dark Matter mystery.
The soundtrack was created by SpaceWave - Cosmic Relaxation.

gave him a sub 🤩
subscribed!
Im honored to be a part of your extremely professionally composed video. I'm half through. It's very interesting and greatly narrated. You rock Sam.
Subs.. and thanks for all your work on this one and all the past and future vids.
Mate you are my legend!
I just saw a notification of this and im so exited watching this
It just bothers me that I sign and PAY for streaming services, and their documentaries are not 10% nearly close to this channel`s in terms of quality, information, progression of explanation, and so on. Thanks SEA for creating such amazing content.
A lot of the paid documentaries are over-produced, I guess in an effort to give people their money's worth.
Instead they just become more boring and bloated than the stuff done by single individuals just trying to provide the information in an entertaining and informative manner. The paid ones have fancier graphics and expert testimonials, but it's often times more distracting than helpful/interesting.

That’s why I have CZcams premium instead of Netflix
thats why I dont pay for none of that stuff. its a get over. everything on CZcams now lol
I've opted out of a lot of my subscription services over the last year for the same reason.
That said, what I've started doing is just donating small amounts of money to a few channels that I really like and that have genuine content creators that do it as a job. I think I've been giving SEA a few bucks a month for a year or so now, even though I don't have to to watch his stuff, but on the flip side I'd rather torrent a show than pay Netflix to watch it.
This is high tier content that is constantly improving and I hope you enjoy creating it as much as we enjoy being mesmerized by it.
This
I hope he follows his heart too
Thank you so much for the donation!💙
It’s ok
Nah Not really. Not Bad but faaaar away From Close to 'high tier'^^
I literally have watched almost every video on your channel twice. It’s amazing. You’ve expanded my knowledge and interest on Astronomy more than school ever has or could. Thank you so much man.
twice? those are rookie numbers, gotta pump them up lmao
@@arsalan2231 lol
Twice!! I reckon I watched/listened to some of the 100 times
All of the multiple
Only twice?! ;)
Even the clown vid?
Too incredible & informative of a production for this to be free. Hardly blinked throughout. Thanks again SEA!
Thank you so much for the donation!! glad you enjoyed it!!
@@sea_space hey that one guy from gd six years ago again xd
As someone who uses Space Engine in my own videos.. I can confirm that you sir…are an ABSOLUTE BEAST at capturing the best shots from this engine. Well done mate👌
Your videos are rather good too. Well done homefry👌
@@darksu6947oh thanks!
SEA is the best CZcamsr for space content.
Facts
FACT
Agreed. Although I do quite like Anton too.
Im writing this as i watch this 20 minutes after release. And so far it’s absolutely incredible. Cant wait to watch it again tonight. You have me immersed with every video you put out and I cant help but watch them multiple times.
No one does it like SEA. I especially appreciate the no sponsor format (rare these days). I joined as a YT member to hopefully keep the channel sponsored free!
I've only recently stumbled across this super awesome niche of youtubers making absolutely incredible documentaries on astrophysics, and you sir are definitely one of the best.
I wouldn't call it a niche they get millions of views, if you've only just found these channels cool worlds and astrum are two other great creators
I want to suggest Anton Petrov.
Ein mehr fisch 🐟
SEA is certainly one of the best
Just putting it out there like the rest of us: this channel is freak'n AWESOME. So well done. Thanks SEA, keep up the great work! :)
Woah woah watch your language
Superb as always. Special thanks for describing competing theories involved. It's impossible to keep up with the different directions of thought on these complex problems so it's very nice to have a source that condenses and presents these concepts, even at the most basic level.
I watch your videos every week. Sometimes daily. Its my happy place lately. Always interesting and making me think. Thanks!
Your content is so good...just top tier content. Thank you for everything you do.
Thank you so much for the donation, glad you enjoy it!!
Thank you for making CZcams better
Listening to these videos as I lay in my bed, falling asleep, is something I genuinely look forward to. It's far beyond educational, and is almost spiritual. You're doing an exceptional job.
Been waiting for this one. Always impressed with the quality … and we get this for free.
I listen to SpaceWave's art all the time, especially when going to sleep and meditating. They have a talent and ear for atmospheric ambiance, love their work as well as yours man! Please keep it up! 😊
I've been using the music for writing these videos recently!
thank you little Nick! 😊
This is such a great channel. SEA and Cool Worlds are hands down my two favorite and have the highest quality presentations along with excellent narration without the dumbed down bs that assumes their audience is watching their very first science video, no cringey clickbait titles and without the super dramatic sounding narrator that sounds like he belongs at a monster truck rally.
Well said
I can't stress enough how good your Videos have been and have become, besides a few other channels like Event Horizon and maybe PBS space time you have become a must watch channels for every New video. And I really appriciate you making those longer Videos... thanks from the bottom of my heart!
New SEA video LFG
Thank you so much for the donation!
Finally, a new video! Truly a ray of light for me lol, life's been pretty hard lately and astronomy is one of the things that keep me going
Thank you so much, your videos are very interesting to watch and they are also very well made♥️
Same!
I hope you’re doing well. Times are different, that’s for sure. This channel is a breath of fresh air and I’m glad it’s bringing you some joy.
Dark matter and its discussion always seems to attract the crazies in some form or another. I think it's name has some role to play in that - it sounds vague, ominous and has scifi connotations. If it was called something less scary like non baryonic matter, it wouldn't get half the attention.
We only have indirect evidence of it's existence bc we don't have any instruments that can detect "non baryonic" matter. The example I always use is that early scientists believed that light could only travel through a medium. So to solve the problem of light traveling to us from the sun they came up with the non-dectectable aether. Which we now know is nonsense and light is free to travel in a vacuum, no medium needed. So to call people that question dark matter "crazies" is weird imo. Just because a bunch of smart people agree on something doesn't make it true. Dark matter may very well be some undiscovered property of space-time itself.
@@randomcharacter6501 I don't think I was clear enough about what I meant. I wasn't criticising people who question it, but rather the small but vocal bunch who use it as means of criticising astrophysics, or physics in general. The types who accuse scientists of making stuff up to paper over the cracks in their models, claim the scientific model is broken, or this is the last gasp of a fundamentally broken model etc
@@diverguy3556 Oh I see you clearly see what’s going on. You left off research money.
You're definitely right.
"Dark matter" sends peoples imaginations into a tizzy.
It also is often people who are furious at the notion of something existing that we cannot see/prove primarily due to the comparisons it draws to religion.
Yeah even in sci-fi shows they use it in such crazy ways. Can't think of which show, but recently was watching something where they were about to navigate their ship through a "wall of dark matter". People get the concept of what it is wrong an awful lot
So excited for the video concerning Dark Energy!
Thanks
Always a great day when the YT notification pops up that SEA has a new release. I plan my whole evening around it. Thank you again for being the best channel on here.
Was planning to take a nap this is perfect timing
I am always truly exited to see a new video from this channel is released
This video reminds me of why I could never study physics, and how grateful I am that there are people out there that understand this stuff so much better than I ever could
I find myself glued!. This is extremely well done Sam. I'm impressed!
I have some gas if you would like to remove the glue from yourself. Gas is pretty good at removing glue, but it's a little rough on your skin. It would suck to be stuck in one spot all the time.
Thank you for making the brilliant soundtrack! A splendid job between the two of us I'd say :)
Going to bed peacefully in the dark night listening to this video about dark matter.
This has got to be one of the top three videos you've never done.
I just want to thank you for this channel. It’s always a beautifully produced and fascinating watch. Thank you!
These videos are special.
special mention to the camera man travelling through the universe getting these amazing images
Hilarious and original comment.
Thank you so much for the amazing quality content you bring to us!
Agree. I'm looking forward to the Dark Energy program.
This content is worth watching in 4K!
Thanks for this masterpiece!
Sorry please bear with me. 4K quality will be available in a couple of hours tops, not sure why it’s not already available, CZcams have been long about processing 4K quality lately
@@sea_space I don't think he was complaining, but good on you for caring.
Great breakdown, amazing visuals, and top notch audio to tie it together. Can’t wait for your next video!
Thank you so much for the donation!
@@sea_space Got to agree with this assessment. I expect it takes a lot of research and attention to detail for production. But I can say that its very much appreciated and the path to follow as its pays off. Looking forward to the dark energy video.
Every time you talk about the beginning of the universe my brain just melts. Like it's incredible to imagine the grand scale of it all. And you gave some new and cooler animations to it! Despite having heard of and learned of dark matter from multiple sources, this was a great video and even added a few new details for me. That dark energy video is going to be wild!
Please never stop making these. This video is the best explanation I've heard. I finally understand how to think about dark matter.
After I watch the video full through for the first time, I always find myself coming back to your videos to help me sleep. Thank you for all the hard work you put in; it's absolutely fascinating to learn about and really easy to relisten to! I would love to see a video on the making of strange matter; though you mentioned it in your types of matter video, I think a deep dive into the subject would be awesome! You're one of my favourite channels, keep making awesome content!
I use your videos to sleep. It's perfect😴
But sometimes they are so interesting that I listen to them again to understand everything
I just finnished all SEA videos. You know what I did? I start looking for science journals I could order. School never made me this curious about physics & cosmology.
The amount of research you must obviously put into these most wonderful video documentaries is baffling. Thanks for another multi sensory masterpiece that keeps us eagerly waiting for the next beautiful release!
Fritz Zwicky, cosmologist
‘One of his favorite insults was to refer to people whom he did not like as "spherical bastards", because, as he explained, they were bastards no matter which way one looked at them.’
Thanks! I do not deserve this high level content for free, brother. Big up for the soundtrack, too.
Thank you so much for the donation!!
These videos are not only very informative, but also great for falling asleep to.
Your time and care really shows with these video essays. So much detail and methodically planned. Well done!
I was so worried something might have happened to you since I haven't seen a new video in a while. Glad you are alright and I'm glad there is a new video to watch. Most people don't have time for a 40 min video but for me, the longer the better. Every second I watch your video, I get great joy. I even listen to your video to fall asleep. Not sure that is a wise thing to do bc now I need it every time to fall asleep. Better than sleeping pills so thanks.
Another perfect addition to the catalogue of SEA.... long may he reign! 👑
Whoohoo, checking every day for a new video. Finally!! Keep up the great work, best channel by far! Greetings from Holland
You’re amazing, there are no words for your content and the effort that goes into it. All I can say is THANK YOU Sea. Favourite CZcams ever . I have learnt so much from you and I appreciate all the videos
SEA’s videos should require seat belts. Because you need to be strapped in while viewing.
These are always fantastic and I hope you know how much of a service you do both for educating and entertaining us.
Another brilliant video. Can’t wait for the sequel
This is so good. Incredible on a 75” with sound system. Great work!
Breathtaking. Beautiful sound and graphics, comprehensive explanations of contemporaneous theories, great narration. Bravo.
Your content never fails to entertain, inform and impress. Thank you for all the hard work.
Thank you so much for the donation, really appreciate it 💙
I remember the old videos he would speak so softly and hypnoticly I would usually fall asleep at some point regardless of how interested I was. He sounds more like a teacher or public speaker these days and it really does make a difference in my ability to enjoy these videos.
SEA!👋 Honestly, there is only one documentary channel I get excited about when a new video is approaching, like the old days when you were checking out what's on TV later, and you say "oh hell yeah my show is on tonight!" So a very sincere thank you 🤘🤓
🌊🌙🌌🌠🪐⭐
Thankyou my sleepless nights are over once again!!!! I've watched like every video a few times since I love listening to these at night and sometimes I miss half the video the first time :)
your content is unbelievable! truly inspireing!
I just LOVE this channel! Keep bringing the EPIC content guys, you're all amazing humans!!
With that said, when can we start watching for part 2, "Dark Energy" to drop?!? 😄 Thanks again!!
Finally a full length video after so long, and i do have to say those hubble deep view and gravational lensing image are truly incredible indeed.
I find your videos so interesting and concise that I’ve taken notes from your transcript. Your explanation is excellent, just when I am wondering what you are talking about, you go on to explain it in simplified terms. Love your work. Keep on ❤
Seeing this guys video on my YT feed LITERALLY makes my week. ALL THE TIME! Keep up the great work dude!!!!! When I saw it came out, I got goosebumps!
I cant express how much I love your channel. Professional, Discovery channel quality videos! Better than even! Thank you.
This is undoubtedly my favorite channel on CZcams.
I love this channel, I watch every video I can. It's an incredible mix of well explained science aimed at a broad audience together with superb narration and cool sound and graphics that keep you watching even in cases like this video which is more advanced and hard to understand. I particularly liked "the scale of the universe" and the one about super voids. I have learned so much just by watching these videos.
Just letting you know I love this format. I always watch the new videos once while awake to really enjoy them and to make sure there are no startling sounds randomly in there. This video I have watched over 10 times while going to sleep. You're delivery has gotten way better over your career. I think you have found a good cadence with your speech rhythm compared with some of your older videos where you sounded rushed. Good job man! Seriously brother, you're doing great work.
I have a recommendation for a video by the way. The sleep time space narration genre is real and youtube monetizes premium subscribers per watch time so you could make a 3 to 4 hour video with the same background music style of the last 3 full length videos. I and probably many of your viewers/subscribers (going by the comment sections) would watch that one 3 hour video every night for months. And people who sleep with youtube on I would imagine are already Premium because ads are loud.
Anyways love the content man, keep up the great work. Much love from America.
Thank you for the kind words, and also for the interesting recommendation. It’s a good idea but I don’t think I could handle 3-4 hour videos. Making a 40 min one is a pretty relentless task over a month from research to publishing. A 3-4 hour one would not only take months but it would probably kill me 😂
I have however been contemplating a kind of similar idea for a sub milestone, possibly 1M subscribers, which is basically a 6-part series of 40 min - 60 min videos uploaded at the same time. that will also take at least 3 months in itself
Let’s get to 1 million goddamnit SEA deserves it if anybody
Wishing you luck and thank you for your videos!
Another outstanding contribution to my edification. Thank you so much for the wonderful work you do!
Whenever I put one of your videos on I first take notes from it, then I rewatch it just for the pure joy that it brings me. You have a really soothing voice. Also, I don't know how you manage to explain things so clearly and with such clean-cut exposition without ever sounding boring. You're the best! Cannot wait for the video on Dark Energy!
came back to your channel after years, since the gd days, and your content had gotten SO much better, love it to bits
Keep up the great work!
Thank you for the donation!!
@@sea_space I just love your videos. I definitely think they are much better than big budget films. Your very talented 😁👍
There is no Dark Matter, we just don’t completely understand gravity.
Agreed
I think the scientists would agree aswell. Dark matter is the name given to the phenomena and it's been misconstrued so much in sci-fi over the years that most people have the wrong idea and think it's an actual physical thing that can be touched
Amazing video! I really appreciate the amazing articulation of details and how you made things understandable. I love astronomy, but I’m not a scientist with basic understanding of physics concepts, and you totally nailed this. I understood a good 90% on first watch. I’ll watch again and get more. Thanks!
Wtf.. I can't sleep without these videos. Please don't stop.
Amazing quality as always. I love this channel!
Well done!! Worth the effort you obviously lavish on your projects. Best channel on CZcams when it comes to space!! Excellent work!
Must be so time consuming to conduct all the proper research and also producing such well made videos with the visuals. Also John Michael Godier and his Event Horizon channel is wonderful.
I really can’t comprehend why a big production studio hasn’t hired you to make documentaries. Quality absolutely insane
Because it doesn’t feature “scary”, “frightening” UFOs, Orbs, Dogmen or Bigfoot. Which is what they think Joe Blow wants. Or will accept!
They are only interested in mass appeal drivel. Every wonder why people doing idiotic things get 35 million views, and real science videos only get tens or hundreds of thousands of views? We are becoming an idiocracy.
This video is GLORIOUS! Thank you, SEA!
I'm so excited for this!! :)
Maybe the real dark matter is the friends we made along the way
Wow man, first time someone actually explained what dark matter was. Thank you so much
Your video, “The Cosmic Scale,” has launched me into loving astronomy again. You and Astrum make such incredible content and you should be proud man. Excellent stuff.
Enlightening information. Thank you for putting together these videos. I can't get enough of them
Hey, how do you get the kitty in a box emoji? :3
@@rarebird_82 Underneath the comment box where you type, there is a smiley face icon to click on to show emotes. It's a default youtube emote
How can you even positivity narrow it down to mass and it not being a unknown force?
Bc introducing a new force would break our models of physics way more than an extra particle haha
It is always so long till the next Video, but it is everytime worth waiting for the Videos, I hope you continue your journey.
Literally the best explanation of this elusive mystery I've seen. Been following your channel for a long while now, mate! Keep up the amazing work!! :D
Looking forward to your next video on dark energy. This is fascinating. Thank you.
This is the easiest to understand explanation of Dark Matter I've watched to date.
This has to be the most articulate way to explain what we see... or don't. Incredible work. Thank you.
I must say, without any hesitation, this channel is better produced than most multimillion dollar budget tv shows and documentaries.
Btw, you should call the next video "the dark energy enigma"
SEA you are amazing, your space videos always fascinate me. There's so much out there in the vastness :D
Yes! A new video, Thank you buddy! The subjects and the quality of videos are amazing, your pace, tone of voice, and calm british accent help peeps stay calm as their minds are blown! between your channel, and Jason Kendall's lectures on cosmic objects my grasp on cosmology, physics and the observable universe have improved.Now, if the fawking math equations and predictions would work themselves out....like the sounds also SEA!
YES! A new upload from SEA! Gonna watch this a few times now ^^
I wonder if we can work out proper theories for quantum gravity will it shed some light on the dark matter mystery? Because for such a large quantity of missing mass you would think we would have more information on it. I really think quantum gravity will open up the answer to this
I agree. I’ve always thought the addition of X amount of dark matter to make the spin calculation add up always seemed a bit arbitrary. Watched a video lecture on quantised inertia a while back that seemed an interesting alternative tho it got tied to the debunked ‘M’ drive somehow losing it credibility. I’m guessing it’ll probably be several things working together & not just one particle.
@@RexCalliber Yeah this is my gut feeling too. It won't be solved by just discovering gravitons, or by gaining understanding of a new field equation. There are going to be multiple moving parts to this which may include a discovery of gravitons, but that will be working in tangent or alongside quantum gravity or like you said with that quantised inertia. I just have a real strong feeling it could have something to do with unifying the theories. "The Theory of Everything"
It seems apparent something is missing or wrong with current DM&E research. Be funny if you’re right.
There's something really spooky about the fact we spend our entire lives outnumbered by an entity we cannot see by 6:1. It gives me the same vibes as sleep paralysis 😅
Think of it like this - it's a good thing that this matter is hidden from our view - we wouldn't be able to see our hand at the end of our arm with dark matter blocking everything around us
SEA is one of the few channels that attempts to answer or explain the difficult questions. Most other places just blind the viewer with science jargon and leaves them more confused than when they started!
Thanks for your astonishing work, amazing as always. I've been waiting a long time while rewatching your videos over and over, and over again. I can't wait for the next, specially with the dark bilogy in hand. Hope you enjoy some holidays and be back with your magic! Thanks pal.
It's basically cosmic ash left over from the big bang. So chemically inert and lifeless that finding microscopic dark matter in the void of space ain't exactly easy.
On a side note, I still like the theory that the big bang was a white hole, and the bigger more massive black holes lead to the formation of healthier new universes in a never-ending cycle of reality perpetuating itself.
And the way everything in the universe seems to have a greater role and purpose in the grand scheme of things is quite fascinating. I always like it when the macroscopic nature of the universe mirrors the relative microscopic nature of life on a planet.
Always thought that white hole theory was really cool. I really do believe there are other universe's out there. Nothing we have ever observed has been singular in the universe, there's always multiples. So I just don't see why the universe itself wouldn't follow this rule.
